How to Intall macOS 13 Ventura on Second Partition

macOS 13 Ventura is the next major release of the macOS operating system, scheduled for release in end of 2022. With this new release, Apple is introducing a number of new features and improvements, including a new Spotlight, Stage Manager, a new System Preferences experience, and more.

If you’re interested in trying out macOS 13 Ventura early, you can do so by downloading the developer preview from Apple’s developer website or by enrolling in Apple’s beta software program. Keep in mind that this is pre-release software, so it may be unstable and contain bugs. As such, it’s not recommended for use on your primary Mac. In this article, we’ll show you how to download and install macOS 13 Ventura on a second partition.

If you want to try out a new version of macOS, or if you need to use an older version of macOS for compatibility reasons, you have to go through the hassle of uninstalling the current operating system and then installing the other one.

This post is also a method to help you run a dual macOS on your Macbook. By following these simple steps, you can have two versions of macOS installed on your computer at the same time and switch between them as needed.

Why Install macOS 13 Ventura on a Second Partition

There are a few reasons why you might want to install macOS 13 Ventura on a second partition. Perhaps you want to try out the new features but don’t want to risk stability issues on your primary Mac. Or, maybe you’re a developer who needs to test apps and features on the latest beta releases of macOS.

Whatever your reason, it’s relatively easy to set up a dual-boot system with macOS 13 Ventura and your current version of macOS. This way, you can switch back and forth between the two operating systems as needed.

For me, I never plan on actually using a new macOS as my primary operating system. Instead, I just wanted to create a partition so that I could test out the new features and see how they worked. If I found something that I really liked, then I would upgrade my main partition to the new macOS. Otherwise, I could just boot into my old partition and continue using it as normal.

The process of creating a second partition and installing macOS 13 Ventura is relatively simple. However, there are a few things that you need to keep in mind before you get started.

macOS Ventura Compatibility

Make sure your Mac is compatible with macOS 13 Ventura. You can find a list of compatible Macs here.

Back Up Your Mac

Before you do anything, it’s always a good idea to back up your Mac. This way, if something goes wrong, you’ll be able to restore your data from the backup.

There are a few different ways that you can back up your Mac. You can use Time Machine, which is built into macOS, or you can use an external hard drive or cloud service.


Make sure your Mac has a good battery life or is plugged in, as the process of creating a second partition and installing macOS Ventura will require your Mac to be turned on for an extended period of time.
